Tech Tree
I would like to take a spin on discussion away from the heavy tank issue, which I believe is secondary to trying to get a working tech tree that isn't limited in success to just the few top nations.
I was thinking about how could we develop a tech tree that would be accessible to most major nations (those with 100+ IC), but not result in those with loads of IC gaining techs that are classified as late war before the war actually begins.
Basically, we have to find a way for hich IC nations (those with 300+ IC), to be able to research a balanced tech tree yet not get substantially ahead of those nations who have high IC but not as much to spare on research (those with 100-200 IC). Basically the problem is that those nations with low IC levels can barely focus on 2-3 different techs, while those with high IC levels can easily spread out their tech research in many places, or can concentrate and get really far in a few critical techs. Basically those with loads of IC can get to the techs that lower supply costs, increase industry size, decrease research cost/time, etc. well before those that have lower IC levels, just increasing the disparity.
We must find a way to STOP major nations from 'cheating' and getting too far in technology in limited areas, as well as allowing for an affordable system that has low IC nations achieving sufficient research.
We all know that the 'Gold' techs, or 'even numbered' techs, like 2000, 2300, 2400, etc. cost a lot of IC, and take a lot of time, and are basically theoretical techs that open a new thought or military process. Currently they take about on average 180 days and 20 IC to research (doctrines are at about 300 days and 40 IC, virtually out of reach of low IC nations). High IC nations can easily focus on many of these 'Gold' techs as well as work on the applied tech that is opened up by these techs. Unfortunately, lower IC nations cannot afford to do both, so while they are researching applied theory (i.e., an actual Basic Medium Tank 40mm), a high IC nation is researching applied and theoretical (i.e., Improved Tank and Basic Medium Tank 40mm). So, in 1 year the low IC nation has a Basic Medium Tank 40mm, the high IC nation has the Basic Medium Tank 40mm, and Improved Tanks and is starting to research the Improved Medium Tank 70mm...
Usually it took about 2 or so years to develop a tank (irregardless of national IC) test theories based upon field testing of your own units, as well as testing of captured and foreign equivalents. However, this testing is almost constant. You are continually testing your own and other equipment throughout development of actual products. Basically, when you finally make something it really is obsolete. Lower IC nations are forced to stop all theoretical research and focus purely on producing the tech at hand.
What I propose is that we drastically cut the cost of these 'Gold' techs, to something almost completely insignificant, like 1 IC, but significantly increse the TIME it takes from about 180 days, to about 600-720 days. So, once you research "2300 # Basic Tanks", you immediately start on "2400 # Improved Tanks", as well as start researching the requirements for the applied part of the Basic Tank technology, that being a basic tank. This would be done by both High and Low IC nations, as both can afford it and to do practical tech research. The High IC nations will just be able to do more (i.e., get Basic Light Tank, Basic Medium Tank, Heavy Tank Battalion, Light Tank Destroyer 50mm, while the Low IC would get Basic Medium Tank and Light Tank Destroyer 40mm).
The low cost would keep every nation constantly researching these theories, and the high time would limit exploits by high IC nations. Since the high IC nations can afford the comparably expensive (20 IC) yet fairly short (100 Days) that the 'Gold' techs currently are, AND research applied techs at the same time, I say we stop this skipping ahead by drastically increasing the minimum time of researching the gold techs, but making the cost insignificant.
Some 'Gold' techs like "2500 # Tank Applications" shouldn't take 600 days to research, since they are mainly improvements on existing designs.
This will stop nations having MBT's by 1941, since the minimum time would be 8 years if they have 900 IC or 100 IC, it will be a minimum that almost every larger nation could afford. Wether or not they could afford all of the applied tech is another thing.
What I want to see is the major nations, like Germany, the US, and Russia sitting around with 100 or so surplus IC that CANNOT be used researching technology because there currently isn't anything to research at the moment! Or, they decide that "well, since I cannot develop tanks any further until I get Advanced Tanks, in about 200 days, I might as well do balanced research and devote some IC into the nuclear program.
Sure, the high IC nations will have more technology, but they cannot jump leaps and bounds ahead in one field like they currently can. They will just fill out their current techs better (i.e., develop a Basic Light Tank and Basic Medium Tank instead of just a Basic Medium Tank) than lower IC nations, but will not have technology significantly more advanced very fast in the game like they currently do.
To gain a 'Gold' tech, you currently spend 20 IC every day for 180 Days, for a total of 3600 IC used.
Under this new system a 'Gold' tech costs 720 (or so) IC for the total research (1 IC for 720 days). Even if the cost was doubled (2 IC for 720 days for 1440 total IC spent) it would still be less than half the total cost of the original version.
High IC nations can afford this high cost-low time, low IC nations cannot. With longer timespans, and very low costs, almost any nation can research Basic Tanks (and have a working tank) by 1939, and Improved Tanks (and have a working tank) by 1942, but nobody will have a Basic Tank by 1938 and an Improved Tank by 1939 (like you currently can in the original system). The main difference between a High IC nation and a Low IC nation in technology is that the Low IC nation will have good research (in both theoretical and applied) in 5-8 (hopefully) of the 14 tech areas, while High IC nations would have good research in 10-14 of the areas.
Low IC nations could afford the critical Industrial and Electronics techs, yet also keep up on a few of the important military techs and not be left behind. High IC nations won't find themselves with advanced technoogy early in the game, but instead of focussing on just a few tech areas, they have a much more balanced coverage.
